APPARATUS FOR MAKING COFFEE.

Specification forming part of Letters Patent lie/50,4112. dated October10, 1865.

following is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing bad to the accompanying drawing-forming part of thisspecification.

The present invention relates to certain new and useful improsements inthose apparatuses' employed for making coffee in which steam is used toextract its aromatic qualities; and it consists in a novel arrangementofparts, by which .the steam, as fast as generated, is passed into thechamber containing thecofi'ee, with which itcomes in contact, and, beingcondensed, penetrates through it, thereby entirely extracting its aroma,which finally passes out and into any suitable'vessel or otherreceptacle to receiv it.

In accompanying plate of drawing my i01 provements are represented, thefigure thereof being a central longitudinal vertical section of thesame.

a a,inl the drawing represent the main-or body portion of the apparatus,in which they water to be evaporated into steam is placed, having acover, h, oyer its upper end, with an aperture, 0, in its center, overthe projection d of which is screwed the cofl'ee-receptacle f, made asfollows:

g is a hollow truncated cone, perforated on Q its sides, and attached byits smaller end to and upon the upper surface of the bottom or socketplate, h,-by which i it, is screwed to the vessel a, as beforedescribed." 'To the upper] end of the cone gis secnredthe cylindricalportion I, over which tightly fits aicover, m, having its central part,n, made, of a conical shape 0 is a vertical tube passing through thecenter of the socket-plate h, and egrterrding'nearly to the bottom .ofthe vessel on atone end and to the upper part' of the conical portionnof the cover at at the other,'terminating in a conical-shapednozzle, p,thereat-V Incasing' thecotfee-receptacle f, arranged.

esdescribed, is an outer covering, q,;fi tting within the raised lipq,entirely put-rounding the top plate or cover, b, of the pot, havinggroove or gutter, .9, connecting with which a the point t of the sameis'a delivery-spout, t which may be made of any desired length an size.

When the apparatus is to be used, the cofi'ei receptacle and its outercovering are first d1 tached from the same and water, either hot c cold,as may be desired, placed within the mai or principal receptacle not theapparatus, who the colfe'emecept'acle is attached to the samt asdescribed, with the reqnisite and desire amount of coli'ee in itsconical perforated chair her a, over which and upon its tube 0 is placethe perforated plate so, having a conical-shape funnel, y.Theoutercovering, q, is then place npon'the apparatus,"whe n it is setupon th stove or other heating device for generatinsteam from thewater'in it, which, as fast a generated, passes out of the same throughth aperture 2, at or near the cover 1), into the tuli o, and up throughthe same, being delivere at its nozzle 1) to the coffee-chamber a; whereas it becomes condensed by impinging agains the sides thereof, it flowsthrough the ape: tures of the perforated plate w, and, perm eal ing the'coflee under the'same, extracts the arc ma therefrom, and then escapesinto the chair her of the outer covering, and,e'nte'ringand fill ing itschannels 8, flows through theydelivery calshape at, .its;c.entralportion, as described and represeutedinthedrawing, a more eve;difi'usionofthe' condensed steam'is secured t the cofiee than wouldoccur were it made of: flat shape and, mo'repver, the conical-shapenozzle to" the s'team pipe prevents the cor 'densed; steam. fromentering the same, the ad vantages of which are evident,
